Abstract
The utility model discloses a single-rail switching mechanism with four parallel bars, which overcomes the defects of big moving size of parallel double tracks, big space usage and unwieldiness of the bypast technology. The utility model has the advantages of simple structure, high reliability and compact rail switch mechanism. The utility model comprises a fixed straight rail, a fixed curved rail, a moving straight rail, a moving curved rail, a fixed support frame, a fixed hinge, an electrical machine, a reducing gear, a crank, a draw rod and a connecting rod which form a set of crank link mechanism and a parallelogram linkage mechanism. The utility model has the advantages of small swinging amplitude in the work process and small space usage. Because of the hinge connection, the transmission efficiency is high, the driving power is small, and simultaneously the dead point position of the crank link mechanism is used.
Description
The utility model relates to a kind of track switch mechanism.
At present, used track steering hardware on the track of transfer car and the automatic production lines in the rail switch plant automation tiered warehouse facility of all kinds single-track vehicle break-in, the track switch mechanism that all adopts double track.Parallel movable is all adopted in its not co-orbital connection.This structural volume is big, and occupation space is big when mobile, heaviness, and actuator all adopts the feed screw nut transmission of band self-locking, and driving efficiency low (less than 50%) is so the power that consumes is big.
The purpose of this utility model provides a kind of simple in structure, compact parallel four-bar gyrocar track switch mechanism.
Technical solution of the present utility model following (seeing accompanying drawing):
It includes fixing straight rail 1,19, fixed bend rail 2, and moving straight rail 3, moving curved rail 4, fixed support 5, fixed hinge 6,7,12, motor 8, fixedly balladeur train 9, coupler 10, retarder 11, crank 13, moving hinge 14,16,18, connecting rod 15, pull bar 17.Wherein electrical motor 8 makes fixed hinge 12 rotate after retarder 11 slows down by coupler 10 imput power sources.Crank 13 is fixed on the fixed hinge 12, and constitutes a piston crank mechanism by moving hinge 14 and connecting rod 15.One side of moving straight rail 3 and moving curved rail 4 is installed on the fixed support 5 by fixed hinge 7 and fixed hinge 6 respectively, and their opposite side is by moving hinge 18, pull bar 17 and moving hinge 16 connect together, and constitute a parallelogram lindage, are connected together with piston crank mechanism by moving hinge 16 again.
When crank 13 rotates, swing around fixed hinge 7 and 6 separately by moving straight rail 3 of connecting rod 15 drives and moving curved rail 4, until putting in place on request, finish fixing straight rail 1 and fixing straight rail 19 or fixed bend rail 2 and the connection of fixing straight rail 19, thereby satisfy the straight-line travelling or the turning driving of vehicle.
When moving straight rail 3 is connected fixing straight rail 1 and fixing straight rail 19 or moving curved rail 4 and is connected fixed bend rails 2 with fixing straight rail 19, crank 13 drivening rods 15 also just in time go to its left and right two limit positions (two dead center positions) respectively, at this moment, the transverse force that no matter acts on moving straight rail 3 and the moving curved rail 4 has much, all can not change track bonded assembly tram, guaranteed the reliability of work.
Accompanying drawing is a structural representation of the present utility model.
Fixing straight rail 1, fixed bend rail 2, moving straight rail 3, moving curved rail 4, fixed support 5, fixed hinge 6,7, electrical motor 8, fixedly balladeur train 9, coupler 10, retarder 11, fixed hinge 12, crank 13, moving hinge 14, connecting rod 15, moving hinge 16, pull bar 17, moving hinge 18, fixing straight rail 19.
The switch mechanism of the present invention and parallel movable relatively has following characteristics:
1, this mechanism structure is simple, compact;
The amplitude of 2, swinging in the course of work is little, and it is little then to take up room;
3, utilize chain connection, transmission efficiency height (greater than 80%), required driving power is little;
4, utilize the dead point location of toggle, not only reliably but also convenient.
Claims (2)
1, a kind of parallel four-bar gyrocar track switch mechanism, include fixing straight rail 1,19, fixed bend rail 2, moving straight rail 3, moving curved rail 4, fixed support 5, fixed hinge 6,7,12, motor 8, fixedly balladeur train 9, coupler 10, retarder 11, crank 13, moving hinge 14,16,18, connecting rod 15, pull bar 17 is characterized in that its motor 8 links to each other with coupler 10, and retarder 11 joins with coupler 10 and fixed hinge 12 respectively, crank 13 is fixed on the fixed hinge 12, constitutes piston crank mechanism with moving hinge 14 and connecting rod 15; One side of moving straight rail 3 and moving curved rail 4 is installed on the fixed support 5 by fixed hinge 7 and fixed hinge 6 respectively, opposite side is by moving hinge 18, pull bar 17 and moving hinge 16 connect together, and constitute a parallelogram lindage, link to each other with piston crank mechanism by moving hinge 16 again.
2, parallel four-bar gyrocar track switch according to claim 1 mechanism, its feature is when connecting fixing straight rail 1 and fixing straight rail 19 or moving curved rail 4 and connect fixed bend rails 2 with fixing straight rail 19 when moving straight rail 3, crank 13 drivening rods 15 go to its left and right sides two limit positions.
